afclaims. (c1: 8373) My invention relates to new and useful improvementsin a pan. for cement mixers, and :haslforbne of its objects to provide adevice :of this character which may be directly attached to a cementmixer and needs no special attention whilein use. 1

Another :object of the invention is i to provide a pan for adjustableconnection toa cement mixing machine whereby drippings from the spout orbucket will be intercepted before reaching the finished or partlyfinished worl z 'on which themachine is resting.

" Anotherobject of the invention is to provide means for adjustably andhingedly mounting the pan on a cement mixing machine; whereby it maybefadjusted vertically for the accommodation of certain classes of workand the positionof the bucket above said pan and whereby it may bemovedto diflerent angularoperative positions -as Well as to an inoperative.

.yide. a pan to be .carried by the mixer. at a position beneath thespout and below the location of the bucket when the latter is beingfilled so that :said pan-catches all drip from the mixer and bucket, .sothat it may be replaced in the mixer or shoveled into the bucket,thereby providing "a. considerable saving in material whichis usuallylost. In additionv to :the saving of :material, .there is also aconsiderable saving in labor where "the device is used in connectionwith a mixer on roadawork because it eliminates the undesirableaccumulation of. cement-on the concrete road bed which must be removedprior to said road bed being covered with the final smooth coating ofcement.

With these and other ends in view, this invention consists in thedetails of construction and combination of elements hereinafter setforth and then specifically. designated by the claims. 5 n aInorden-that those skilled in the art to which thisinvention appertainsmay understand how i130 make and :use the same, I will describe itsnonstnuctionrin detail, referring by numerals vto this application, inwhich:--

In carrying out; my invention asfherein 1cmbodied, It. represents acementmixingrmachine of any usual'or well known construction:includ--.ing amixingdrum' I I in which the materials are mixedand then allowedto "run out 'rover 'or through the spout l 2 into any suitablereceptacle .such1as :abucketl3 supported =on3- any suitable crane 14. Inthepart'icular conventionallyiillustrated mixer herewith shown, thebucket l'3i'is .moved in and out on a boom and :is moved back beneaththe but'ererid' of thespout 12 'when said bucket is tolbe 'filledwiththehoe- .inentitious material :coming Jfrom 'the fimixi'ng drum.

On some suitable part .jof the mixing machine below the'spout 12 arefixed suitable angleiron hangers 15 by means of bolts =l'6 or equivalentfastening devices. i v

There :are a pair of these hangers-and they conventional cement mixershowing my inven Y are mounted so that one flange of each projectsinwardly or toward the otheruhanger .and the flanges. by which thehangers are fastened to :the machine have any desirable number rof holeswhereby they may .be' used in "connection with diiferen't machines inwhich the supporting 'elements for the hangers vary 'in heightfromthground or tread base of the Lmachine.

The other or outwardly projectingor free it flanges of the hangers havea number of holes i! in vertically spaced relation for the reception ofpintlebolts vl8 for hingedly supporting the pan IS in any desirablevertical adjustment. The pan" I9 includes afiat bottom wall Milfashioned to provide a wide body portion 2land areduced neck 22 at therear whereby recesses are provided at each side of the neckxto the rearof the body. for the accommodation of caterpillar ytreads wheels and thelike, and the rear edges of the body 2| of the pan between the sideedges of said body and the side edges of the neck are preferably angularor extend in oblique directions inwardly and rearwardly from the sideedges of said body.

On the top face of the pan bottom around the edges thereof, with theexception of the is preferably higher than the upstanding flange i ofthe rim 23 because when shoveling material out of the pan, said materialis generally forced toward and into the neck portion and therefore islikely to be piledup to a greater height than when seeking its levelover the entire pan.

In order tofincrease the height of the rim or sides of the pan in theregion of the neck, angular side plates 25 are secured to the rim 23 atboth sides of the neck and extend from the extreme rear end or edge ofsaid neck along the sides of said neck and short distances on to theoblique rear edges of the pan body as plainly shown in Figs. 2 and6,'and on the outer faces of said side plates at the rear ends aremounted vertical strengthening strips 26 and the pintle bolts l8 passthrough said strengthening strips and side plates, thereby hingedly'connecting the pan to the hangers l5 whereby the outer end of the panmay be raised or lowered as desired. By turning the pan up until itis'in a substantially vertical position, it willbe out of the way whenthe mixing machine is being transported from place toplace.

On the under surface of the bottom of the pan are two parallellongitudinal runners 21v which are preferably spaced apart a distanceequal to the width of the neck so that the downwardly projecting flangesthereof are practically in alignment with the side edges of said neckand the other flanges project toward each other as shown in Fig. l. Thebottom edges of these runners are beveled or inclined upwardly fromtheir inner toward their outer ends as illustrated in Fig. 5, so that ifthe pan strikes a high spot or an obstruction in its path of travel, itwill ride over the obstruction without injury to the bottom of the pan.

The said runners 2'! also strengthen the pan and help to stiffen thesame lengthwise thereof and in order that said pan may alsobe'strengthened or siifened transversely, an angle iron rib 28 issecured to the bottom face of the pan bottorn between the runners andother angle iron ribs 29 are secured to the bottom face of the panbottom between the runners and the outer edges of the body of the pan asshown in Fig. 4.

When it is desired to slightly elevate the pan and more particularly theouter end thereof,

this may be accomplished through the medium of the set screws 30 havingthreaded connection with the inwardly projecting or fixed flanges of thehangers l5, the said set screws 35% passing through the hanger flangesand impinging against the rear of the pan at points below the pintlebolts [8. By screwing in on the set screws 30, the pan will be swungupwardly any desirable distance within the limits of the screws and byreversing said action, the pan will be lowered and therefore said pancan be adjusted so that the bucket will just clear the rim thereof andplace the pan in such close proximity to the bottom of the bucket thatvery little splashing will occur from the material running out of thebucket and falling on to the pan.

With a pan such as herein described in position as shown in Fig 1, anyof the cementitious material dropping from the bucket, either throughthe cracks in the dump bottom or running over the upper edge, as thesame is being filled, or any of the material which may be splashed aboutduring the filling of the bucket, or that may drip from the spout afterthe bucket 'has been removed from beneath, the latter will drop or runinto the pan, and therefore, will not reach the finished or partlyfinished work and can be removed from the pan at any time and shoveledinto place or into the bucket or replaced inthe mixer, thereby providingsavings in time, labor and material.

Of course I do not wish to be limited to the exact details ofconstruction as herein shown, as these may be varied within the limitsof the appended claims without departing from the spirit of myinvention.

Having thus fully described my invention What I claim as new and usefulis:- k

1. In combination with a cement mixing machine including a deliveryspout leading from a mixing drum and a conveyor bucket to be filled fromsaid spout when the former is disposed beneath the latter, hangersattached to the machine and including inturned flanges through whichsuitable fastening means pass for securing the hangers in place andfurther pro- ,vided with outwardly projecting flanges with nection withthe inturned flanges of the hangers and engaging the rear portion of thepan below the hinge points for tilting the pan into any desiredposition.

2. The structure set forth in claim 1 in combination, with runnersmounted on the bottom of the pan longitudinally thereof and having theirbottom edges inclined upwardly toward the outer end of the pan.

3. A device of the kind described including a pan body, a pan neck, anupstanding rim formed from angle irons surrounding the edges of the bodyand neck, side plates secured to the side rims of the neck, verticalstrengthening strips disposed over the outer faces of the platesadjacent their rear edges and runners disposed in parellelism on theunderside of the pan body and neck.

4. The structure set forth in claim 3 in combination, with ribs disposedtransversely on the underside of the pan body adjacent its inner edgesand across the imaginary line of meeting between the pan body and neck,

5. A pan for cement mixers comprising a bottom produced from a flatsheet of metal fashioned to provide a body and a restricted neck, a rimsurrounding the edges of the body'and the side edges of the neck andformed from an angle iron secured to the top face of the bottom, thatportion of the rim extending across the rear 10 formed from angle ironswith the flanges which 3 contact the bottom being turned inwardly towardeach other and the downwardly projecting flanges being inclined upwardlyfrom their rear toward their forward ends and ribs also formed fromangle irons and disposed on the I under face of the bottom between therunners and between the side edges of the body and said I runners.
